Myinvention relates to a process for the manufacture of resinous condensation products from phenols and formaldehyde which are clear as water. It is well known to b produce condensation products from phenols and formaldehyde and such is preferably effected by the use of condensing agents. The object of the present invention is to produce an article of this kind clear as water and such aim is attained by the use of chloraminoaldehydes as condensing agents.

In accordance with my invention I dissolve chloraminoaldehyde in formaldehyde and boil it with the proper quantity of phenol with a reflux cooler for some time. After the reaction is completed and after the removal of the water present the initial condensation product can be converted into the final condensation product by the usual methods.
